104 Safety functions
Step Description
1
The SLS request is received. The motor speed is above the SLS limit. The drive starts
to ramp down the motor speed. The SAR1 parameter
defines the deceleration
ramp slope until the speed reaches the SLS limit. The FSO starts the SAR1 ramp
monitoring (parameters
). SAR1 configuration defines the target and
monitoring limits for the deceleration ramp (
Note:
If parameter 200.112 has value 0, the drive (drive parameter 23.23) defines the
ramp.
2
The drive trips on a fault, there is a drive power loss, or user stops the drive by coast
stop. SAR1 monitoring of the FSO is switched off. SLS Modoff delay time starts
(parameters
&
).
delay starts.
3
Modulation of the drive returns. FSO activates SAR1 monitoring again with same
ramps as when the SLS request was set.
4
The Modoff delay time limit. If the modulation would not return before this time, see
previous case.
5
The FSO starts the SLS monitoring when the motor speed is in the middle of the SLS
limit and the SLS trip limit (see also section
How to fine-tune when monitoring is started
on page
), and stops the SAR1 monitoring. The SLS indication (parameter
SLSx.15, SLSx.24, SLSx.34 or SLSx.44) goes on.
